Engadget mentions that the September launch "lines up with what we've been hearing, as we've been told that the first device will actually be the leaked HTC Vision QWERTY slider (pictured above) that's been popping up in the wild lately.

AndroidCentral writes that "the device will be able to hit the full 21 Mbs speed that so far has only been possible on aircards. While HSPA+ isn't technically 4G, it's pretty darn fast and can be put in place without any new hardware" which is definitely a plus for T-Mobile customers.

Phandroid adds that the road map lists a device by HTC releasing in September called the Vanguard. They think "that phone very well could be the recently-imaged HTC Vision with its slide-out QWERTY keyboard"
